Soros’s hedge fund, Soros Fund Management LLC, boosted its so-called “put” position on the exchange traded fund market’s biggest and most widely traded fund, the SPDR S&P 500 ETFSPY5.LN -0.53%, known by its ticker symbol SPY. The ETF tracks the broad S&P 500 stock index.
Mr. Soros held put options linked to 7.1 million shares of SPY as of Dec. 31, compared to about 2.8 million shares at the end of the third quarter, according to a filing with the Securities and Exchange Commission. The value of that position jumped to $1.3 billion, up from $470 million, and made up about 11.1% of the fund’s holdings, by far the fund’s biggest position.
